The concept of gradual implementation of smart grid through the distributed generation integration

The emergence of distributed generation (DG) introduces a new level of dynamism in the distribution network. Network becomes the most dynamic part of power system altering frequently its status from consumer to the source. The existing remote control system isn´t able to track those changes, nor reliably control the system. Permanent solution is the smart grid. However, significant resources (and time) required for the systematic introduction of smart grid delay the implementation of these ideas. The paper is based on the principle that one should take advantage of any equipment already available in the network (e.g. smart meters). The lack of equipment, especially in initial stages, should be compensated by calculations and advanced engineer reasoning. The idea is to monitor the points of energy injection into the local network and to monitor one control point (the "weakest” point) in line, which is the indicator of voltage problems, and based on this information, to define the mode of DG control, and, by that way predefined autonomous control of each DG, to control the situation in local network.
